Hello, I am reaching out regarding the use of EDNS Client Subnet (ECS) in BIND. Context: I am testing an environment where:
* A dnsdist server receives client queries and injects a specific ECS (e.g., 41.226.22.0/24). * These queries are then forwarded to a BIND 9.18-S1 server configured as the final resolver. Issue: BIND does not forward the ECS to upstream servers and does not preserve this information in responses. Questions: * Can BIND 9.18-S1 be configured to rewrite or forward an ECS injected by dnsdist? * If not, which version or configuration would you recommend for BIND to meet this requirement? Best regards Sami,
